近日,中国地质大学地质过程与矿产资源国家重点实验室赵来时教授团队在国际著名期刊《Geochimica et Cosmochimica Acta》发表题为Raman spectral, elemental, crystallinity, and oxygen-isotope variations in conodont apatite during diagenesis(牙形石磷灰石的拉曼光谱、元素...
This conference aims to promote the exchange of new ideas among the leading experts from industry, academia, and government on the controls and impacts of inorganic and organic diagenesis on mudstone ...
Travertines and calcareous tufa are porous deposits formed by interactions between ambient precipitation of calcium carbonate and resident organisms under different temperature regimes. The distinctio...
Weathered zones in quartzitic bedrock on the Hak alancˇearru Mountain on the Varanger Peninsula, northern Norway, have been examined, as has the timing of their development. The weathered zones are ma...
Bacterial biomarkers (D-amino acids and muramic acid) were investigated in surface sediments (0–1 cm) at 22 stations in the Peru margin. Concentrations were used to quantitatively estimate the relati...
Amino sugars and amino acids, including the bacterial biomarkers muramic acid and D-amino acids, were measured to investigate the diagenetic alterations of and microbial contributions to detrital org...
期刊信息 篇名 Diagenesis of magnetic minerals in the intertidal sediments of the Yangtze Estuary China and its environmental significance 语种 英文 撰写或编译 撰写 作者 Zhang Weiguo,Lizhong Yu.S.M.Hutchinson 第一作者单位 刊物名称...
会议信息 篇名 Diagenesis of magnetic minerals in intertidal sediments of the Yangtze Estuary, and its relationship with heavy metal pollution 语种 英文 撰写或编译 撰写 作者 Zhang Weiguo,Yu Lizhong 第一作者单位 华东师范大学 会议名称 Fun...
To provide new insights into the early diagenesis of extracellular deoxyribonucleic acid (DNA) and its relevance in trophodynamic processes, we collected sediment samples from a variety of coastal and...
We applied a diagenetic model to examine the effects of a decadal-timescale progressive decrease in bottomwater oxygen concentration on sediment geochemistry and fluxes across the sediment-water inter...
Changes in the D/H ratio of sedimentary organic matter (SOM) during thermal maturation have been difficult to interpret because the effects of hydrogen exchange and kinetic fractionations are c...
Using a multicomponent inverse model, we quantified the rates of organic matter (OM) remineralization and the relative importance of major terminal electron acceptors [Fe(III)-(oxy)hydroxides and SO4-...
We studied the role of photochemical and microbial processes in contributing to the transformation of dissolved organic matter (DOM) derived from various plants that dominate the Florida Everglades. ...
Changes in the size and neutral aldose (NAld) composition of phytoplankton photosynthetic products during the early diagenetic process were experimentally examined using 13C as a tracer. Most (94.7%) ...
Polyphosphate (poly-P) was detected with the use of 31 P nuclear magnetic resonance (NMR) spectroscopy in sediments from a large variety of lakes with different trophic state and morphometry. In th...
